单选题 ______ the flood, the ship would have reached its destination on time.

A. In case of
B. In spite of
C. Because of
D. But for

【正确答案】 D

【答案解析】虚拟语气。根据主句中would have reached its destination判断，该句应该是一十虚拟条件句表示与过去事实相反，因此选择but for，表示“要不是……”。in case of意为“假设、万一”； in spite of意为“虽然、尽管”；because of意为“因为”，均不符合句意。
